Oracle's founder Larry Ellison has gone as far as to describe the transport app company as "almost worthless".Manuela Saragosa speaks to Scott Galloway, professor of marketing at NYU Stern School of Business, who says the company's problem is that it is a great brand and great app that have been built upon a fundamentally unprofitable market - ride hailing.

Cement and concrete have one of the biggest carbon footprints of any industry, and eliminating it is no easy task.By volume concrete is the most heavily used resource by humanity apart from water. Our houses, offices, dams, roads, airports and so on all depend on pouring vast quantities of this magical, versatile material. But not only does making cement - the glue that binds concrete - involve huge amounts of energy. The chemical process itself also produces carbon dioxide as a bi-product, and nobody yet knows how to avoid that.Manuela Saragosa speaks to three people who offer partial solutions. Architect Simon Sturgis of pressure group Targeting Zero wants to design most of the concrete out of buildings, and recycle what's left. Benjamin Sporton, chief executive of the Global Cement and Concrete Association, is trying to coordinate global research efforts. Meanwhile Professor Mohamed Saafi of Lancaster University says the answer may lie in carrots and sugar beet. Producer: Laurence Knight(Picture: A shoe pr

Fenella Barber of China business consultancy Bao Advisory says it is typical of the cultural misunderstandings that still occur when Western businesses try to break into the country's gigantic fast-growing consumer market. But Andrew Coflan of geopolitical strategists Eurasia Group says the kerfuffle says a lot more about internal Chinese politics than the business environment, which Beijing is actually working hard to make more foreigner-friendly. Meanwhile journalist and businessman
